Eww, nothing worse than florescent lights in a 'kitch' kithcen....don't listen to the above answer. Incandescent bulbs in recessed cans, can be dramatic, especially in 'special' places in your home. Can lights are directed downward, but the distribution can be adjusted by the type of bulb you use. They are wonderful!
121 sf is a really small space, and your layout seems perfectly fine! You may want to lay out your lights in a pattern that will be most effective for functional purposes: perhaps instead of the lights at the 4 corners, center a light above the sink, and another near a counter you know you will be doing a lot of food preparation. The other lights should be spaced throughout to give you enough even luminosity in the rest of the kitchen. But as i mentioned before, 5 lights sounds good for the space you have! It is better to have more recessed cans than too little, after you are finished, and you find it is too bright, you can use lower wattage bulbs, or unscrew 1 or 2 lights...if you installed too little fixtures, that can't be adjusted...higher watage bulbs will create a cave like appearance.
